Detailed Description

Write text into file.

This class allows a comfortable output to a file only by using the elementary system calls open() / write() / close() and (optional) fsync(). The class is derived from OutputStream.

Constructor & Destructor Documentation

FileOut()

FileOut::FileOut ( const char *  path )

explicit

Constructor.

Opens the file for writing using the system call open().

Parameters

path	Path to the output file

~FileOut()

virtual FileOut::~FileOut ( )

virtual

Destructor.

Close the output file (using the system call close())

Member Function Documentation

count()

static int FileOut::count ( )

static

Number of output files which are currently opened (with this class)

Returns

Number of active files

flush()

virtual void FileOut::flush ( )

overridevirtual

Write the string to the open file.

The implementation should only use the system calls write() and fsync().

Implements OutputStream.

getPath()

const char* FileOut::getPath

(

)

Get path of the output file.

Returns

Path to output file (as defined in constructor)
